[0049] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some of these specific details. The description of the embodiments is merely intended to provide a better understanding of the present application through showing examples of the present application.

[0050] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The embodiments will be described in detail below with reference to the accompanying drawings.

[0051] At present, with the increasing progress of display technology, OLED (Organic Light-Emitting Diode) display panels have gradually become the mainstream development direction. The local brightness display unevenness of OLED (i.e. Mura phenomenon) is one of the problems that need to be overcome in the development of OLED.

[0052] In order to overcome the local brightness display unevenness of OLED, a Demura algorithm is configured in the driving chip of the OLED panel in the related technology, so that the Mura defects existing in the display panel can be alleviated with the aid of pixel optical imaging technology and software algorithm. The principle of the Demura algorithm is to use the Gamma characteristics of the display panel to make the pixel points of the overall panel perform compensation action according to the target brightness with the average brightness as the target brightness.

[0053] The inventors have found through long-term research that the related technology can alleviate the Mura phenomenon existing in the display panel. However, this processing method has the following problems:

[0054] Since the driving chip and the display panel are usually manufactured by different manufacturers, the related technical solution makes it difficult for the display panel manufacturer to control the optimization direction. In order to realize the optimization of the display effect, there may also be a debugging requirement during the manufacturing of the display panel, so the display panel manufacturer has a self-research debugging requirement.

[0055] In addition, the Demura debugging algorithm of the driving chip is limited, for example, for G-toward Mura or S-toward strip Mura, the Demura algorithm debugging of the driving chip is poor. The S-toward strip Mura is a strip Mura region extending along a first direction, and the first direction can be the extension direction of the Source of the display panel. The G-toward Mura is a Mura region extending along a second direction, and the second direction can be the extension direction of the Gate of the display panel.

[0056] Therefore, the embodiments of the present application provide a data processing method, a data processing device, a data processing equipment and a computer storage medium, thereby solving at least one of the above technical problems. First, the data processing method of the embodiments of the present application is introduced as follows.

[0057] Reference is made to Figure 1 In an optional example, the data processing method comprises:

[0058] S110, obtaining first original data and target brightness of each pixel point in a display panel;

[0059] S120, performing brightness superposition on the first original data of each pixel point according to the target brightness of each pixel point to obtain second original data of each pixel point;

[0060] S130, displaying according to the second original data of each pixel point.

[0061] The embodiments of the present application obtain the first original data and the target brightness of each pixel point in the display panel, then perform brightness superposition on the first original data of each pixel point according to the target brightness of each pixel point to obtain the second original data of each pixel point, and then display according to the second original data of each pixel point. Therefore, the optimization of the first original data is realized, thereby providing a debugging solution based on the first original data, which can improve the Mura phenomenon and help to alleviate the problem of limited driving chip debugging.

[0062] In some optional examples, in S110, the first original data can be obtained by optical imaging of the pixel points of the display panel, and then captured by a camera device, such as a CCD camera (Charge Coupled Device Camera).

[0063] It can be understood that the original data is the measured brightness of each pixel point at the original gray scale via the camera shooting. In the related art, the original data is usually directly input into the driving chip for Demura. In the present example, the original data can be first original data, which can include the first brightness of each pixel point at the original gray scale.

[0064] The target brightness can be a constant. The target brightness can be set according to different display panels, or can be related to different pixel regions in which different pixel points are located. For example, different pixel regions correspond to different target brightnesses, or in some examples, the target brightness can be the average brightness involved in the Demura algorithm mentioned above.

[0065] In some optional examples, in S120 to S130, the algorithm debugging can be performed according to the target brightness, so that the algorithm debugging effect based on the target brightness can be superimposed into the first original data to obtain superimposed second original data.

[0066] The storage module of the subsequent display panel can be programmed according to the second original data of each pixel point, so that each pixel point can display according to its own second original data. Thus, the display panel manufacturer realizes self-research debugging of the original data, which can meet the debugging needs of the display panel manufacturer and meet the debugging optimization direction.

[0067] In addition, for the special Mura that cannot be considered in the Demura algorithm using uniform compensation in the related art, the present application performs self-research debugging on the original data to obtain the second original data after debugging, and displays the second original data, which can process the special Mura. Thus, the uniformity of the display panel is improved, and the display effect is improved.

[0068] It should be noted that the brightness superposition optimization scheme for the original data of the present application can increase new application scenarios, which will be described in detail in the following examples.

[0069] Please refer to Figures 2 to 4 In order to more clearly illustrate the beneficial effects of the present application, the following will be described in combination with specific use scenarios.

[0070] Among them, Figure 2 The effect diagram obtained after programming and verification of the test diagram superimposed on the first original data by the above embodiment is shown. Thus, the effect diagram can be superimposed in advance by processing the original data, and the debugging time of the driving chip manufacturer for configuring test diagrams and compression ratio parameters is shortened.

[0071] Figure 3The scene when the UDC (Under Display Camera) sub-screen appears Mura phenomenon is shown. The first original data can be superimposed in brightness to obtain second original data, and after the second original data is verified by burning, the special Mura phenomenon can be solved.

[0072] Figure 4 The position of S-shaped band Mura is shown. After the algorithm debugging of the driving chip, the Mura in this special position still exists obvious S-shaped band Mura of red and green. By superimposing the first original data in brightness to obtain second original data, and after the burning verification of the driving chip, the problem can be solved, thereby alleviating or even eliminating the Mura in some special positions, improving the brightness uniformity of the display panel, and improving the display effect.

[0073] The following describes the first original data of each pixel point including the first brightness of each pixel point at the original gray scale.

[0074] In some optional examples, referring to Figure 5 In the above S120, the process of superimposing the first original data of each pixel point in brightness according to the target brightness of each pixel point to obtain the second original data of each pixel point can include:

[0075] S510, calculating the first gray scale compensation value of each pixel point under the standard brightness according to the target brightness of each pixel point and the first brightness of each pixel point at the original gray scale;

[0076] S520, converting the first gray scale compensation value of each pixel point under the standard brightness into the second brightness of each pixel point under the standard brightness, and the second brightness is the second original data.

[0077] The standard brightness is the display brightness of the display panel in the standard brightness mode.

[0078] In the present example, the process of how to debug and optimize the first original data, realize brightness superposition, and then obtain the second original data is given, which can be applied to the case that the driving chip debugging is limited in the related art, helps to shorten the debugging time of the driving chip manufacturer, improves the Mura phenomenon, improves the brightness uniformity and display effect of the display panel, and improves the problem of limited driving chip debugging.

[0079] Optionally, the first gray scale compensation value of each pixel point under the standard brightness can be calculated by the following formula (1).

[0080] N x =N*(L aver / L n ) 1 / Gamma (1)

[0081] Where, N x The first grayscale compensation value for a pixel under standard brightness, where N is the original grayscale value, and L is the grayscale value. aver For the target brightness, L n Gamma represents the first brightness of a pixel at its original grayscale level N, and Gamma is the grayscale coefficient value for standard brightness display.

[0082] The first grayscale compensation value mentioned above is the grayscale value that needs to be achieved after adjustment and compensation. For example, please continue reading... Figure 4 For the S-direction Mura of the notch screen, the target brightness can be set for each pixel within a local small block within the S-direction Mura range. The first original data of this area can be converted using the above formula (1) to output the first grayscale compensation value N of each pixel. x This allows for gradient compensation of the Mura at the screen edge in the S direction.

[0083] As can be seen from the above example, the calculation of the first gray level compensation value has taken into account the target brightness, and the debugging and optimization of the original data has been realized. That is, this embodiment provides an effective means for brightness superposition.

[0084] In some alternative examples, the process of converting the first grayscale compensation value of each pixel under standard brightness to the second brightness of each pixel under standard brightness may include:

[0085] The first grayscale compensation value of each pixel under standard brightness is converted into the second brightness of each pixel under standard brightness using the following formula (2).

[0086] L n1 =(N x / 255) Gamma1 *L 255 (2)

[0087] Among them, L n1 N represents the second brightness of a pixel under standard brightness. x L is the first grayscale compensation value for a pixel under standard brightness. 255 Gamma1 is the display brightness value of a pixel at grayscale 255, and Gamma1 is the actual grayscale coefficient value of the pixel.

[0088] It should be noted that when the original data is applied to the driver chip, it is presented in the form of brightness. Therefore, the gamma formula mentioned above, i.e. formula (2), can be used to convert the first gray level compensation value back into the original data to obtain the second original data.

[0089] In the calculation of the second original data of each pixel point, a set of Gamma1 can be used for brightness conversion in full screen. For example, Gamma1 can be a constant, such as 2.2 or 2.3.

[0090] It can be understood that L 255 The value of L can be 2, which is not limited here.

[0091] In this embodiment, a method for brightness superposition to obtain second original data is provided, which facilitates subsequent driving chip to generate a burning file by means of the second original data for burning, and finally can display according to the second original data of each pixel point. Thus, a debugging scheme based on the first original data is provided, which helps to improve the Mura phenomenon and alleviate the problem of limited driving chip debugging.

[0092] In some optional examples, the display according to the second original data of each pixel point in S130 can include:

[0093] The second gray scale compensation value of each pixel point is obtained by performing brightness compensation on each pixel point according to the second original data of each pixel point; and the actual gray scale value of each pixel point is taken as the second gray scale compensation value for brightness display.

[0094] In this example, after obtaining the second original data, the driving chip performs brightness compensation on each pixel point according to the second original data of each pixel point, and outputs the actual gray scale value according to the obtained second gray scale compensation value. Thus, the Demura compensation of the display panel is realized by taking the second original data as the input of the driving chip. The debugging optimization of the original data and the brightness compensation of the driving chip are combined, and the brightness display effect brought by the final second gray scale compensation value is the superposition of the Demura effect of the driving chip and the brightness compensation effect of the original data. Therefore, the display effect of the display panel is improved by combining the two compensation methods, and the phenomenon of uneven display is improved.

[0095] Optionally, the brightness compensation on each pixel point according to the second original data of each pixel point to obtain the second gray scale compensation value of each pixel point can include: substituting the second original data of each pixel point into a Demura formula to obtain the second gray scale compensation value of each pixel point.

[0096] The Demura formula can be set according to actual needs, which is not limited here, as long as the original data participating in Demura is the second original data. For example, the Demura formula can refer to the following formula (3).

[0097]

[0098] Ln1 is the second luminance of the pixel point under the standard luminance, N x is the input gray scale value of the pixel point at L n1 is the input gray scale value of the pixel point at L aver is the target luminance of the pixel point at L n1 is the target luminance of the pixel point at L aver is the average luminance of the display panel), N x1 is the second gray scale compensation value of the pixel point under the standard luminance, and gamma is the actual gamma value of the pixel point.

[0099] The process of performing luminance compensation by taking the second gray scale compensation value of each pixel point as the actual gray scale value of each pixel point can include: obtaining a data voltage value corresponding to the second gray scale compensation value of each pixel point; and burning a register value corresponding to the data voltage value into the display panel.

[0100] It should be noted that the storage module in the display panel can include registers of each sub-pixel, and the register value stored in the register corresponds to the data voltage value of the driving transistor in the pixel point. The actual gray scale value can be converted into a corresponding data voltage value, and then a corresponding register value is obtained to complete the burning. Finally, the effect of double debugging and optimization by the driving chip and the original data is displayed by referring to the second gray scale compensation value corresponding to each pixel point, which further improves the display effect of the display panel and improves the luminance uniformity of the display panel.
